Negative Numbers
Real values of less than nothing

Of course, using our new definition
b − n = ( 1 )/( b n )
we can write
( 1 )/( 8 ) ( 1 )/( 23 ) − 3 .
Now, since
16 = 24
and
( 1 )/( 8 ) − 3
as we have just seen, our problem can be rewrittenas follows:
16 × ( 1 )/( 8 ) ( 24 ) ( 2 − 3 ) .
Now, applying the rule for multiplying two powers of the same number, ( b m ) ( b n ) = b ( m + n )
